Trail Ridge (U.S. 34): This road through Rocky Mountain National Park is the highest continuous auto road in the country. Itâs truly an all-American icon â the road itself is listed on the National Register of Historic Places.
Lumber Dimensions. 2x4s are not actually 2 inches by 4 inches. When the board is first rough sawn from the log, it is a true 2x4, but the drying process and planing of the board reduce it to the finished 1.5x3.5 size. Here are the common sizes of lumber, and their actual sizes.
For a small deck (10x12 feet, for example), determine how much lumber you'll need by counting all the pieces of each size -- 12-foot 2x4s, 8-foot 2x6s, and so on. Add 10 percent to framing quantities and 15 percent to decking to allow for waste.
